"And what exactly is this 'agenda' of yours?" Lucifer questioned the voice.
"My agenda? Why, my boy, did you never find out about Satan's motives?" The voice questioned Lucifer. "Well, let me educate you. Satan wanted to destroy the multiverse, just like me! Except back then, I was such a 'good little boyscout' back then, too. Damn other half.."
"So you want me to help you---" Lucifer paused for a moment, "destroy the multiverse? What madness is that?!" His energy flared, the Satan Fragment glowing a blood-red.
"Oh, trust me. This isn't madness. This society has already settled for too long with their broken promises of freedom to adapt to anything else. Surely even you get that. Join me, and your dream of an empire under your rule can be realized at last." The voice responded. Lucifer's aura settled down, the Demon Lord having calmed down.
"I understand. And what's in it for you?" Lucifer asked the voice.
"Me? I get to fulfill my destiny, one that these Z-Fighters already delayed once. My former cohorts died, but me-- I won't fail a second time."
